22 Startup - Using a Template AutoCAD drawings are identified by a.dwg extension. When you save a drawing a.dwg extension is applied. AutoCAD drawings are identified by a.dwg extension. When you save a drawing a.dwg extension is applied. However, when you start a new drawing, AutoCAD loads a template file with a.dwt extension. However, when you start a new drawing, AutoCAD loads a template file with a.dwt extension. So What is a Template? So What is a Template? Standardized file formats with preset internal variables. Provided by AutoCAD or created by user. Limits (drawing length & width) Limits (drawing length & width) Text Height Text Height Dimension Scale Dimension Scale Linetype Scale Linetype Scale

26 Saving Your Work! As you work on an AutoCAD drawing, all data for the drawing resides in RAM memory on the computer. As you work on an AutoCAD drawing, all data for the drawing resides in RAM memory on the computer. If you close the AutoCAD session or some other misfortunate event occurs, ALL DATA WILL BE LOST! AND CANNOT BE RECOVERED! It’s enough to make a grown man or woman cry!…that is unless you have SAVED your session! If you close the AutoCAD session or some other misfortunate event occurs, ALL DATA WILL BE LOST! AND CANNOT BE RECOVERED! It’s enough to make a grown man or woman cry!…that is unless you have SAVED your session!

27 Saving Your Work! Top 8 Events that will make you cry! 1. Accidentally exiting AutoCAD. 2. AutoCAD bugs. 3. Failure of Microsoft Windows OS. 4. Power failure (frequent occurrence). 5. Unrecoverable error in drawing. 6. Network issues or shutdown. 7. Disrupting a network or power cable. 8. Missing an assignment due to above!

28 Saving Your Work! *Important – You should save to a folder on your NETWORK drive (U:) whenever possible! Network drives are backed up daily and can be recovered in the event of system failure. *Important – You should save to a folder on your NETWORK drive (U:) whenever possible! Network drives are backed up daily and can be recovered in the event of system failure. If you save to the local hard drive (C:) and the disk fails you are S.O.L.! If you save to the local hard drive (C:) and the disk fails you are S.O.L.! If you save to your flash drive and loose it, forget it, or destroy it in the wash machine you are S.O.L.! If you save to your flash drive and loose it, forget it, or destroy it in the wash machine you are S.O.L.! Hint: No excuses for late assignments unless its due to a network problem! Hint: No excuses for late assignments unless its due to a network problem!

29 Saving Your Work! Most common ways to Save are the Application menu commands: Most common ways to Save are the Application menu commands: Save & Save As… First time file is saved, a file name must be supplied. Either command brings up “Save As” dialog box for file name entry. First time file is saved, a file name must be supplied. Either command brings up “Save As” dialog box for file name entry. Subsequent saves: Subsequent saves: Save – saves to the existing drawing file name. No prompts or dialog box occurs. Save – saves to the existing drawing file name. No prompts or dialog box occurs. Save As - brings up same dialog box. If new name is provided, data is saved to that new file and current drawing session name is updated. Save As - brings up same dialog box. If new name is provided, data is saved to that new file and current drawing session name is updated.

30 Saving Your Work! Save As Dialog Box: Save As Dialog Box: Selects folder where file is saved Click to browse for a folder Enter file name to save to. Drawing name will update as well. Not necessary to include.dwg extension. Added automatically. Click Save after folder and file name are entered *NOTE: All AutoCAD files have a.dwg extension. This is how you identify them. Moves folder up one level. Pre-existing file name may be selected from this list. File will be overwritten.

31 Saving Your Work! Toolbar Quick Save: saves to the existing drawing file name. No prompts or dialog box occurs. Acts identical to Save from application menu.

32 Saving Your Work! Smart Save Tips: Save often! – it’s a good idea to save after every major change to a drawing. Save often! – it’s a good idea to save after every major change to a drawing. Create sensible file names that indicate the content. Create sensible file names that indicate the content. Create a running history of your save files for each particular assignment or project; Create a running history of your save files for each particular assignment or project; Ex: Assign1_Bracket A.dwg  1st major save Ex: Assign1_Bracket A.dwg  1st major save Assign1_Bracket B.dwg  2nd major save Etc. Create a logical folder structure to save to (from orientation): Create a logical folder structure to save to (from orientation): Create folders for each course (Draft I, CAD I, etc) Create folders for each course (Draft I, CAD I, etc) Create subfolders for assignments.

107 Basic Plotting Basic Plotting Requires Several Steps : 1)Select Plotter – We have two plotters available, so the correct plotter must be selected. We use the HP laser printer, simply called (J5) for CAD I. Do Not use (J5 - Plotter). 2)Select Paper Size – Choose a paper size which is supported by your selected plotter (remember standard sizes from Drafting I?). 3)Specify Plot Area – The entire drawing or just a portion may be plotted. Determine what portion of the drawing to plot. 4)Set Plot Scale – Most drawings conform to a particular scale (i.e. 1:2, 1:4). For our first exercises this is not required, but for later assignments an appropriate scale MUST be used!

108 Basic Plotting Basic Plotting Requires Several Steps : 5)Set the Plot Style Table – Select the More button , then select monochrome.ctb. This ensures all colored lines are black instead of gray scale. 6)Specify Paper Orientation – Portrait  or Landscape . We only use  Landscape orientation. 7)Preview Plot – Often times, the plot will not appear as expected. You should ALWAYS preview the plot on your display screen before plotting. This saves wasted paper and toner (Friend of the Earth…Save a tree)! 8)Plot – Send the plot to the plotter and retrieve your hardcopy!
